While waiting for a UnixPC guru ( ;-) ) to provide the elegant answer,
you could try the kludge below:

1. cu -s<speed> -l<ttyXXX> to a modem set for auto-answer.
2. dial "by hand," e.g., "ATDTXXXXXXX" or it's equivalent.
3. login to the callback modem.
4. after verification, enter the modem's command mode and hang up
   (+++ATH).
5. wait for callback and "login:" prompt.

Note that your modem must not "hangup" the tty line when you hang up the
remote callback machine.  If it does and you cannot configure your modem
to prevent this, IMMEDIATELY "cu" again or try another access program
such as kermit or pcom.
